I have never used the gcc static analyzer and I just found this ICE
accidentally. Please correct me if I did something wrong.

What compiler options do you use? I can't reproduce it with the current master.

--- Comment #2 from David Malcolm <dmalcolm at gcc dot gnu.org> ---
Judging by the URL, it looks like it only happens with the "x86-64 gcc (static
analysis)" option on Compiler Explorer.
I added this in the early phase of the project, but right now it's pulling from
an obsolete and very out-of-date branch.
Sorry about the confusion.
The fix is to either:
(a) file a pull request with Compiler Explorer to remove that option, or
(b) push a more recent version of the code to that branch (e.g. for
experimental options that aren't yet ready for trunk)

godbolt.org now no longer shows "x86-64 gcc (static analysis)" as an option
(unless following a link such as the one in comment #0 which uses it).
Marking this as resolved.
Sorry again about the confusion.
